Sign up with your college email address. If you get an error message, chances are that your college hasn't created an account here. Luckily, you can create one yourself. But you probably won't have to do that.
Once you register, you'll need to confirm your email address. The confirmation email may take up to 10 minutes to arrive (it usually doesn't, though). Simply click on the link in the email, and begin using Movie Moocher.
